SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 480,866, dated August16, 1892.

Application filed October 10, 1891.

To all whom it may concern.-

Be it known that I, WILLIAM HAYwooD DAVIS, a citizen of the UnitedStates, residing at Chapel Hill, in the county of Washington and Stateof-Texas, have invented a new and useful Oar-Oouplin g, of which thefollowing is a specification.

This invention relates to carcouplings, more especially of that classknown as hookand-link; and the object of the same is to effect certainimprovements in devices of this character.

To this end the invention consists in the construction hereinafter morefully described and claimed, and as illustrated on the accompanyingsheet of drawings, wherein- Figure 1 is a perspective view of the end ofa car with my coupling attached, taken slightly froin the upper and leftside of the drawhead. Fig. 2 is a central longitudinal section of twodraw-heads embodying my improvements, a link being shown as coupled into`the right draw-head and supported by a link-lifter. Fig. 3 is a frontelevation Yof one draw-head.A

Referring to the said drawings, 1 designates the draw-head, which issuitably supported beneath the car-body 2, and in the upper side ofwhose open mouth is pivoted a depending hook 3, a spring 4 holding thehook normally vertical, as shown.

5 is a pin moving transversely across the draw-head near the bottom ofits mouth and adapted to pass in front of and retain the lower free endof the hook 3 in place, and this pin has a notch 6 in its body, whichpermits the hook to swing forward and allow the link 7 to pull out whensaid notch is opposite the tip of the hook. The pin is drawn normallyinward bya coiled spring 8 on the left side of the draw-head, and at theopposite side thereof a rod 9 is connected with the pin, passes throughan eye 10, preferably having a roller 11, and is connected at its upperend with a slide-rod 12, moving through suitable guides 13 in the end ofthe car and having a handle 14 at each end. By this construction anoperator standing at either side of the car can move the slide-rod inthe proper direction to draw the pin out and bring the notch 6 oppositethe tip of the hook, when the tension Serial No. 408,289. (No model.)

on the link will cause it to draw out, and when the slide-rod isreleased the spring 8 will cause the pin to return to place and hold thehook in operative position.

The link 7 preferably has a transverse bar 2O at its center, in which isan eye 21, and 22 is a chain having a snap-hook 23 at its end adapted todetachably engage said eye. Journalcd in bearings 24 in the rear end ofthe car is an oscillating rod 25, having handles 26 at its ends andacrank 27 at its contento which the chain is connected. By thisconstruction the'operator standing at the side of the car canmanipulatethe handle 26 so as to lift the' link and guide-it into themouth of an approaching draw-head. If the latter be of the constructionabove described, the free end of the link will bear the hook to the rearand pass under its tip,whe`n the spring 4 will throw said tip down intothe link and lock the latter in place; but it will be understood thatthe link may be locked into draw-heads of the usual construction, andthis I claim as one of the special advantages of this device.

I do not limit myself to the use of a linklifter, nor to the precisedetails of construction or the size or materials of parts, and variouschanges in and additions to this coupling maybe made Without departingfrom the spirit of my invention.

I claim as the salient features of this invention- 1. In a car-coupling,the combination of a draw-head, a depending hook pivotally mountedtherein, a transverse pin arranged on the bottom of the mouth of thedraw-head and provided intermediate its ends with a notch to permit thepassage of the lower end of the hook, a spring for holding the notchaway from the hook, and means for sliding the pin to bring the notchopposite the hook, substantially as described.

2. In a car-coupling, the combination, with the draw-head, a hookmounted on a transverse pivot in the upper part of the mouth of IOO rodguided in eyes in the end of the car, an eye in the side of thedraw-head, and a rod connected at its ends to said pin and rod andpassing intermediately through said eye.

3. In a car-coupling, the combination, with the draw-head, a hookmounted on a transverse pivot in the upper part of the mouth of saiddraw-head, and a spring holding said hook normally vertical, of atransverse pin moving across the bottom of said mouth and having a notchin its bodyadapted to permit the outward passage of the tip of the hook,a coiled spring drawing said pin to bring its notch normally out of theline of said tip, a link having a bar across its center carrying an eye,a chain having a snap-hook detachably engaging said eye, alink-lifter,to which said chain is connected at its upper end, and means for drawingthe pin against the force of said coiled spring.

4. In a car-coupling, the combination, with the draw-head, a hookmounted on a transverse pivot in the upper part of the mouth of saiddraw-head, and a springholding said hook normally vertical, ofatransverse pin moving z5 across the bottom of said mouth and having anotch in its body adapted to permit the outward passage of the tip ofthevhook, a coiled spring drawing said pin to bring its notch normallyout of the line `of said tip, a link 3o having a bar across its centercarrying an eye, a chain having a snap-hook detachably engaging saideye, a link-lifter, to which said chain is connected at its upper end, aslide-rod guided in eyes in the end of the car, an eye 3 5 in the sideof the draw-head, anda rod connected at its ends to said pin and rod andpassing intermediately through said eye.

In testimony that I claim the foregoing as my own I have hereto aixed mysignature in 4o presence of two witnesses.

WILLIAM HAYWOOD DAVIS.
